About QR Forge
QR Forge is a free tool for turning a link into a QR code you can hold — a keychain, a table stand or a wall plaque — ready for your 3D printer.
Why we built it
QR codes are everywhere: on restaurant tables, shop counters, rental-home walls and event invitations. Most of them are stickers or laminated paper that peel, fade and get lost. A 3D printer can make something far sturdier and better looking — but turning a QR code into a two-color, print-ready model usually means a CAD program, a lot of fiddling, and a few failed prints before one finally scans.
QR Forge does that work for you. Paste a link, pick an object, choose your two filament colors, and download a file your slicer opens with the colors already assigned. The aim is simple: your first print should scan.
Who runs QR Forge
QR Forge is an independent project built and maintained by the QR Forge team. The goal is a generator that's genuinely free to use, respects your privacy, and comes with honest, practical guides on getting a printed code to scan reliably.
How it works
- Everything runs in your browser. The QR code, the 3D mesh and the 3MF/STL files are generated on your own device. Nothing you type — including Wi-Fi passwords — is uploaded to us.
- No account, no limits. There's nothing to sign up for, no watermark and no cap on how many codes you make.
- No tracking in your codes. Your QR code contains exactly the link or text you entered — no redirect service in between and no expiry date — so it keeps working for as long as your link does.
- Supported by ads. The site shows ads so the tool can stay free. You can read how that works in our Privacy Policy.
What you can make
The generator exports regular PNG and SVG images for printing on paper or signs, and two-color 3MF or single-color STL models for 3D printing in three styles: tabletop stands, keychains and wall plaques. Popular uses include restaurant menu stands, "leave us a review" signs, Wi-Fi plaques for rentals and offices, and keychain favors for weddings and events.
